How deep can a shadow reach? How much space does a shadow contain?

We imagine a blending of forms, an unconscious search by the viewer for degrees of kinship, following the outlines of paper silhouettes and the gestures of a body that moves and is moved, as their shadows merge. A movement that is at once three-dimensional and two-dimensional. An uninterrupted morphopoiesis, a continuous interplay of light and shadow. And we, unsure of where to stand.

What shape does that cloud in the sky take?
